The purpose of this study was to evaluate the psychometric features of the Chinese version of the developmental dimensional diagnostic interview-short version (3Di-sv). A total sample of 138 children including 79 children with autism spectrum disorder (ASD) and 59 typically developing children completed the 3Di-sv interview. The Chinese version of the 3Di-sv has a good internal consistency (0.94). Test-retest analysis confirmed the instrument's time stability (0.89). The instrument's concurrent validity with the Autism Behavior Checklist (ABC), the Childhood Autism Rating Scale (CARS) and clinical diagnosis was verified; the correlation between total scores was 0.72, 0.82 and 0.90, respectively. The 3Di-sv significantly distinguished between autistic children and non-autistic children in every area of autism symptoms. Optimal cutoffs were derived using receiver operating characteristics curves. Using clinical diagnosis as criterion, overall sensitivity was 98 % and specificity was 90 %. The study determined that the Chinese version of 3Di-sv can well distinguish autistic children from typically developing children.
本研究旨在评估发展维度诊断访谈-短版（3Di-sv）中文版的心理计量学特征。共有 138 名儿童参与了研究，包括 79 名自闭症谱系障碍（ASD）儿童和 59 名正常发育儿童。3Di-sv 中文版具有良好的内部一致性（0.94）。重测分析证实了该工具的时间稳定性（0.89）。该工具与自闭症行为检查表（ABC）、儿童自闭症评定量表（CARS）和临床诊断的同时效度得到了验证；总分之间的相关系数分别为 0.72、0.82 和 0.90。3Di-sv 在自闭症症状的各个领域均能显著区分自闭症儿童和非自闭症儿童。使用受试者工作特征曲线得出最佳截断值。使用临床诊断作为标准，总敏感度为 98%，特异性为 90%。研究表明，3Di-sv 中文版能够很好地区分自闭症儿童和正常发育儿童。
